What is the maximum height a mouse can squeeze through?

The maximum height that a mouse can squeeze through is 1/4 inch. Mice are incredibly flexible creatures with the ability to adapt their body shape to fit through tight spaces. Their ribcage is not rigid but rather cartilage-based, allowing them to compress their bodies significantly.

Many common household openings that a mouse may exploit are often overlooked because they seem too small for any animal, but a gap of just 1/4 inch is enough for a mouse to enter. This adaptability aids them in finding shelter, food, and escaping predators, making them resilient pests in both urban and rural environments. Understanding this can help in implementing effective pest control measures, as sealing even the smallest openings can prevent mice from entering residential spaces.
